This question would generate a number of varying answers, but we're choosing the right to live.
The preservation of mankind and the right and a duty to preserve our own lives is the most basic yet the most important among the fundamental natural rights (life, liberty, and property), presented by English philosopher John Locke.
Article 2: Right to life of the European Convention on Human Rights says:
Everyone’s right to life shall be protected by law. No one shall be deprived of his life intentionally save in the execution of a sentence of a court following his conviction of a crime for which the penalty is provided by law.
Deprivation of life shall not be regarded as inflicted in contravention of this Article when it results from the use of force which is no more than absolutely necessary:
in defence of any person from unlawful violence
in order to effect a lawful arrest or to prevent the escape of a person lawfully detained, and
in action lawfully taken for the purpose of quelling a riot or insurrection.
If humans are to be deprived of their lives, it would be impossible for us to further exercise our rights to preserve our properties and make free choices about how to conduct our own lives.
